The yamaha Air intake for SHO/SVHO watercraft has always been highly restrictive. The small double right angle S hose was never ideal for allowing airflow. This was always a problem.
Then, in 2019 yamaha changed their supercharger wheels to more efficient models. They made too much power for stock form. Yamaha then modified their air filters to be half the old surface area, greatly reducing power.
Shown below is the highly restrictive 2019+ stock Yamaha Waverunner svho intake filter vs the 2017 stock filter. Upgrading your intake on 2019+ SVHO will make a huge difference and this is a big reason why! Yamaha eliminated 50% of the breathing area to cripple your engine.
Perhaps you have already purchased a few items like a solas impeller or MACSBOOST module Pro? Want to upgrade to a Stage 2 Plus but are not sure what you need? Here is a list of all the items in the kit. Don’t miss out on the extra performance, extra fun and extra smiles!
Add a MACSBOOST Module and enjoy a 2 second reduction in acceleration time to 59mph, radically better mid range throttle response and more top speed. Our Module is the best bang for the buck when it comes to performance improvements and is the easiest performance part of all to install. Welcome to MACSBOOST.com
Well, we certainly hope not. We were not able to ship our yamaha intakes 4/17 as anticipated. Parts are stuck at the border. We hope to have them to you as soon as possible. We will keep you posted and keep checking back for updates! We thank you for your patience!

From our Raspberry Pi Case customer Jon Plyler: Hooked up to my KX3 portable station. Pi running headless controlling the KX3 and running digital modes. Pretty awesome setup. The only thing better is if the pi case matched the radio color.
What If we told you that you could install an extra 200RPM using a screwdriver and 5 minutes of your time? Would you do it? What if we told you this was the gain OVER an existing “high performance” intake on a stock class race ski?
Is it Impossible? Could this be fake news?
Our preliminary testing on a 2019 FX SVHO stock prepared race craft with stock intercooler showed a back to back increase of 9100RPM to 9300RPM going from another high performance intake to our exclusive MACSBOOST Velocity Stack Air Intake. Top speed was a blistering 82.5mph
Obviously, your performance may vary, but the increase could be even more dramaticon more highly modified skis. It should also be noted that a performance tune is required to get the full benefit. Stock tunes often work against high performance modifications such as this.
